>>1931907Literally just Emory cloth on a foam sanding block. I dont like chemical baths like evaporust or vinegar. They make the steel look dull and grey, while turning the hardened bit black, creating a contrasting line between the two. It also removes a lot of patina, which is one of my biggest reasons for liking pitted heads. You'll have fresh steel on top and black oxide down in the pits. I love that look. Pic related was equally as corroded when I first found it.
